PCB wave soldering jig for limiting element offset

The utility model provides a PCB (printed circuit board) wave soldering jig for limiting element offset. Including a substrate, the PCB is placed on the substrate. A horizontal limiting block and a plurality of pressing plates are arranged on the base plate; wherein the horizontal limiting block is detachably installed on the base plate, the pressing plate is rotatably installed on the base plate,the PCB is pressed on the base plate through the pressing plate, two clamping grooves which are symmetrically formed and perpendicular to the base plate are formed in one end of an element of the PCB, L-shaped positioning arms which are symmetrically arranged are arranged on the two sides of the horizontal limiting block, and the positioning arms are connected into the clamping grooves in a clamped mode. According to the PCB wave soldering jig for limiting the deviation of the element, the floating problem of the element on the PCB can be solved, the horizontal deviation of the element on thePCB can be limited, and t
